If you sell a physical product in 2026, the shelf you should worry most about isn’t in a store. It’s the one on a phone — the search results and product pages inside Instacart, Amazon, Walmart, Kroger, and the regional grocery apps where your shoppers actually decide what goes in the cart. That shelf runs on something called retail media, and the whole category is buried under jargon that was, frankly, built for people ten times your size.
So here’s the plain-English version. No forty-tab dashboard, no acronym soup. Just the handful of terms that actually decide whether your product gets found and bought — explained the way we’d explain them to you over coffee.
Retail media network (RMN)
Start here, because everything else hangs off it. A retail media network is the advertising business a retailer runs on its own turf. When you pay to show up higher in Instacart’s search, or to get a “sponsored” spot on Walmart.com, you’re buying from that retailer’s RMN. Amazon Ads was first and biggest. Walmart Connect, Instacart Ads, Kroger Precision Marketing, Target Roundel, and Albertsons Media Collective are the names you’ll hear next.
The important part: the retailer owns both the store and the ad platform. That means when you advertise, they can tell you exactly how many units you sold as a result — because the ad and the purchase happen in the same place. No other kind of advertising can do that cleanly. That’s the whole appeal, and it’s why RMNs are the fastest-growing corner of advertising right now.
Sponsored products (and sponsored placements)
These are the paid slots in search and browse. Type “tortilla chips” into a retailer’s app and the first result or two with a little “Sponsored” tag — those are brands paying to be there at the exact moment a shopper is deciding. It’s the closest thing digital has to buying the endcap at the front of the aisle.
For a brand your size, sponsored products are usually where the first real dollars go, because they put you in front of people who are already reaching for the category. You’re not interrupting anyone. You’re just making sure that when someone wants what you sell, they find you and not the store brand.
The digital shelf
Winning the click is only half the job. The digital shelf is everything a shopper sees once they land on your product page: the images, the title, the bullet points, the claims, the reviews. It’s the part of retail media almost nobody talks about, and it’s where brands your size quietly leak the most sales.
Here’s why it matters: a great ad can send someone to a page with one blurry photo and two old reviews, and they’ll bounce straight to the competitor. The retailers know it — their own search ranks complete, well-built pages higher. The digital shelf is also the one part of all this you fully control, which is exactly why we tell brands to tighten it before spending more on ads.
Attributed sales
This is the number that should keep you up at night — in a good way. Attributed sales are the dollars a retailer’s own system credits to your advertising. Instacart, Walmart, and Amazon each record, natively, how much product moved because of the ads you ran. It’s not a model, not an estimate, not a “brand lift study.” It’s the retailer telling you: this ad sold this much.
If a report can’t tie your spend back to product moved, be suspicious. Attributed sales is the honest number — everything else is a vanity metric dressed up in a nicer font.
When we report to a client, this is the figure we lead with, because it’s the one that’s actually real. You should demand the same from anyone running your media.
ROAS
Return on ad spend. Divide the attributed sales by what you spent, and you get a multiple. Spend $1,000, drive $4,000 in attributed sales, and your ROAS is 4. It’s a useful gut-check, but don’t worship it — a sky-high ROAS often just means you were only bidding on people who’d have bought you anyway. The goal isn’t the biggest ROAS. It’s the most incremental product moved at a price that still makes you money.
Share of voice
Of all the sponsored slots for a given search — say “cold brew coffee” — what percentage are yours? That’s your share of voice. It’s a handy way to see how loud you are versus the competition in the searches that matter to you. You don’t need to win every slot. You need to show up consistently in the handful of searches where your shoppers are, on the retailers where you already have momentum.
The one thing all of this is really about
Strip away the acronyms and retail media comes down to a simple loop: get found at the moment someone’s deciding, close the sale on a product page worth landing on, and prove — in the retailer’s own numbers — that it moved product. Do that, learn from it, do it again.
The big national brands spend millions building teams to run that loop. We packaged it for brands your size and made it something you can actually afford — starting where you already win, on the local and regional shelves the big agencies never bother to learn. From the local shelf to national scale, in that order, and on your terms.
If your listings are thin, your ads are off (or off the rails), or you just want a straight read on where your fastest wins are, that’s exactly what a free shelf check is for. Tell us where you sell, and we’ll come back with a plan in plain English.
